Probably the Bio-ceuticals InNatal. You buy from health food shop where they stock naturopath supplies.

I used to use than, but as I cannot absorb folic acid, I now use Seeking Health brand, which I order from the USA. Thorne Research is also a good brand for things like Vitamin D or activated folate. They may have a good pre-natal.

The Elevit type stuff isnt very good, but it's cheap and better than nothing.
